bad touch up or rust bubble

moegd55 · 06-20-2019, 11:27 AM

I was detailing my car and then I sow this. My heart skipped. I'm the second owner. Car has never been hit or accidented according to carfax.

How can i tell if its a bad touch up paint or a rust bubble.

Note: I got it inspected at the BMW dealer but I need your feedbacks first.

That appears to be rust, to me.

I thought galvanized steel won't rust

You'll find out what it is when you have it fixed, which you should do in any event.

BMW accepted to fix it under warranty unsure yet if it's caused by rust or a poor touch up paint .

Looks like a bad touch up.

That's what I'm thinking as well, but what makes you say that? I'm curious

It doesn't look like it was applied to the surface to me - that's why I think rust from beneath the paint. Glad to hear warranty will cover it - you just need a competent shop!

It will be fixed at the bmw dealership. According to bmw and other sources its a bad touch up.

The only way to know for sure also happens to be the very first step in fixing it, wet sanding it to flush. If it's just a glob of touch up paint the only thing wet sanding will reveal is more paint.

I guess ... I'll wait and see what bmw reveals . Makes me hesitate now about getting an anti rust treatment . The car is like brand new and I'm keeping it for a long time, but yet most ppl are not recommending it , including bmw . If it ends to be just a bad touch up paint job , I'm might not do the treatment. I don't know...

I haven't had a car anti-rust treated since my '63 Chevy.

moegd55 · 08-31-2019, 08:25 AM

Got it fixed . It was a bad touch up. Not rust.

Glad it got resolved.

sunshine235 · 10-17-2019, 07:36 PM

Uh oh!! Rust bubble big time!!!

Billfitz · 10-17-2019, 09:36 PM

Not according to the OP per Post #13.

TheBingoBalls · 10-20-2019, 06:44 PM

Surprised BMW even covered that under warranty or decided to just cover the cost. Other than rust, which BMW is still hesitant on covering without a comprehensive inspection, BMW almost never covers these things especially where a touch up was performed.

Good for them for covering this.

Billfitz · 10-20-2019, 08:22 PM

If it was my dealership it would be fixed gratis, under the theory that it shouldn't have gone off the lot like that. It should have been spotted and taken care of as part of the used car reconditioning process.
